使用Unity编辑器类编辑 ToolBar

两种类型的 Toolbar
第一种只显示文字
第二种显示图片

在Editor文件夹下创建脚本EditorScript

using UnityEngine;  
using System.Collections;  
using UnityEditor;  

[CanEditMultipleObjects]  
[CustomEditor(typeof(TestScript))]  
public class EditorScript : Editor {  
  
    private TestScript testScript;  
  
  
    private int select = 0;  
    private int selected = 0;  
    private string[] names = { "one", "two", "three", "four"};   
    private static GUIContent[] myGUIContent = new GUIContent[4];   
    private Texture2D[] myTexture = new Texture2D[4];  
  
    private void OnEnable()  
    {  
        testScript = (TestScript)target;  
        Init();  
    }  
  
    private void Init()  //初始化获取图片  
    {  
  
        for (int i = 0; i < 4; i++)  
        {  
            //通过路径获取图片资源  
            myTexture[i] = (Texture2D)AssetDatabase.LoadAssetAtPath("Assets/MyTexture/1.png", typeof(Texture2D));   
            //将图片数组和字符串数组存进去  
            myGUIContent[i] = new GUIContent(myTexture[i], names[i]);    
        }  
    }  
  
    public override void OnInspectorGUI()  //绘制在Inspector面板上  
    {  
        EditorGUILayout.BeginVertical();  
        //创建 Toolbar  ， 返回值为选中的项， 参数1 为 选中的项， 参数 2 每项上的文字  
        select = GUILayout.Toolbar(select, names);    
  
        EditorGUILayout.Space();  
        EditorGUILayout.Space();  
        //参数 1， 选中的项， 参数2 每项的图片， 参数3 整个Toolbar的宽度， 参数4 Toolbar的高度  
        selected = GUILayout.Toolbar(selected, myGUIContent, GUILayout.Width(300), GUILayout.Height(64));   
        EditorGUILayout.Space();  
  
        EditorGUILayout.EndVertical();  
    }  
}  

TestScript 脚本如下

using UnityEngine;  
using System.Collections;  
  
public class TestScript : MonoBehaviour {  
    public void MyTestA()  
    {  
        Debug.Log("Click");  
    }  
}
